The theoretical and methodological study analyzes human intelligence in its complex structure and evolution in time, in order to identify the possibility of qualitative and quantitative alteration of the “g” factor through programmes of educational development. Taking into consideration the experimental results, most researchers of psychometric orientation consider that general intelligence is a mental capacity determined mostly by heredity and less by education. Cognitive psychologists conclude that human intelligence is influenced by multiple socio-cultural variables (age, education, experience, culture, profession), a fact that determines different levels of performance and success in life. More than this, it was demonstrated that there cannot be only one form of intelligence, be it general, but there are multiple types; this shows that psycho-cognitive conception has surpassed the psychometrical one.
